Product Description:
The MHD093C-035-PG1-AA is a synchronous servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As an electromechanical actuator, it converts drive controller current into rotary motion for positioning tasks in automated machinery, handling lines, and packaging equipment. The motor’s integrated feedback devices support closed-loop operation so axes can maintain commanded speed and position under changing loads. Its synchronous design also supports responsive speed changes and accurate settling during short, repetitive motion cycles. This makes the unit suitable for transfer stations, indexing systems, and other servo axes that require repeatable acceleration behavior.
At standstill, the rotor can deliver a continuous torque of 23.0 Nm, allowing stable holding force during clamped operations without thermal overload. Mounting is aligned by a 130 mm centering diameter that seats the flange concentrically on machine frames. The square flange pattern of 140 / 150 mm matches common IEC interface layouts and supports direct installation on compatible machine surfaces. The mounting geometry also helps keep shaft alignment consistent when the motor is coupled to rigid machine plates or gear units. Heat generated in the stator is removed only by natural convection, eliminating the need for external blowers or liquid circuits. A braking element adds 22.0 Nm of mechanical torque when de-energized so vertical axes remain stationary during power loss.
Position information comes from digital servo feedback and an integrated encoder that reports an absolute (>4096 revolutions) multi-turn value, allowing startup without a return-to-home move after an interruption. Digital feedback also supports stable low-speed regulation and accurate position correction during changing load conditions. The motor falls in size code 093 with length designation C and winding code 035, which correspond to the electrical and geometric arrangement used by the connected drive. Power enters through a connector on side A, which can simplify cable routing where adjacent machine structures limit access. A plain shaft transmits torque without a keyway, favoring clamp couplings that help keep backlash low in indexing tables and other precision servo-driven equipment.
